Protecting HDDs from (external) train vibrations (lemmy.dbzer0.com)

I am worried that externally caused vibrations might damage my HDDs (NAS in the planning). The subway / metro runs under my building, and every time the train passes, this causes slight but measurable vibrations in the 50-100 Hz frequency range. It is more like a rumbling noise than the usual vibration of a passing train.

I've been researching the topic of vibration dampening on and off, and things like sorbothane popped up in my search. I also remember finding foam plates in an eye scorching yellow material.

My plan is to set up the case, fire up a measuring app on my phone (say phybox or the like) and test a few options. But I figured, I can't be the first person to be guarding against outside vibrations. :D

Other than the usual 3-2-1 and backup regularly, what can I actually do? I would like to make sure that the lifespan of the HDDs doesn't get too negatively impacted, so the chances of a catastrophic failure, as well as having to invest 1k EUR every couple of years is reduced as much as possible. Thanks!

HDDs latency will go up from external vibrations (even yelling at your system will do the trick). This would be a good direct source to see if the vibrations are negatively impacting it.
